Flyback Driver At 2KHZ? Answered

I want to drive a flyback i have laying around i have one of these modules:

which can generate 2khz square wave and i want it to drive a mosfet irfp250n which will drive the flyback the problem is the flyback normally runs at 16-25khz and i am doubtful whether the 2khz will to enough to reach the resonance of the transformer

Will it work?

No, you'll saturate the transformer and destroy the mosfet. I don't see why you couldn't modify the board though, to get 25K out of it.

My circuit for the induction heater will drive a flyback at resonance as well - at least for the primary side.
Resonance does not really work well with fixed frequencies unless you can match the entire system perfectly.
